Fixing Ridge Tiles to pitched roof

[BR_1]

I received a quotation from a roofer which stated the old removed ridge tiles would be mechanically fixed to a fitted timber along the ridge line, with the tiles being rebedded in with a 3:1 mortar mix. Any broken tiles would be replaced.

However, when the workman were carrying out works they screwed the ridge tiles directly onto the ridge board passing through the roofing felt.

Should I be concerned they have screwed through the roofing felt through to the ridge board and not onto a fitted timber which the quotation said would also be fitted?

Also does this comply with BS-5534

Thank you palaceray for your reply!

without stripping ridge to check the finished height of the existing ridge board they wouldn't know what timber they may need to fit.
probably your ridge board is set high and maybe the roof pitch made it not necessary to fit additional timber.
how do you think additional timbers are fixed?..... Screwed, Nailed and strapped through the underlay....

Is it common about 5 days after ridge tiles have been rebed that gaps should be appearing between some of the tiles and mortar?

no, post a picture

There is no mortar left on ridge tile casting a shadow - plus the gap is also visible from the other side of the tile.

It looks like the muck has sunk and not bonded properly to the ridge tile.

 

[datarebal]

Agree, mortar slumped away from ridge.

Cheers palaceray and datarebal - is there a common cause for mortar not to bond to the tile and slump away? What should I expect from the installer?
